Hey, I'm Jeroen.

I'm a senior software engineer who builds AI systems for production. Twenty years of engineering experience, now applied to AI agent orchestration and retrieval-augmented generation.

Most recently I built the orchestrator agent for the Google + BBC AI Agents demo at IBC2025, which won the Broadcast Tech Innovation Award. I started studying AI seriously in 2017 with Udacity's Artificial Intelligence Nanodegree, well before the current wave of large language models made it fashionable.

I write about practical AI engineering at herczeg.be/blog and live in Belgium. This book exists because most of what I learned shipping production AI is locked in private codebases, and someone should write it down.
